<p>A <a class="link" href="GtkWindowGroup.html" title="GtkWindowGroup"><span class="type">GtkWindowGroup</span></a> restricts the effect of grabs to windows
in the same group, thereby making window groups almost behave
like separate applications. </p>
<p>A window can be a member in at most one window group at a time.
Windows that have not been explicitly assigned to a group are
implicitly treated like windows of the default window group.</p>
<p>GtkWindowGroup objects are referenced by each window in the group,
so once you have added all windows to a GtkWindowGroup, you can drop
the initial reference to the window group with <code class="function">g_object_unref()</code>. If the
windows in the window group are subsequently destroyed, then they will
be removed from the window group and drop their references on the window
group; when all window have been removed, the window group will be
freed.</p>
